[Car Pit]

Hey guys. I read this string a while back and bought the electronic signal kit from Turnswitch.com. I like the unit overall, but I have had trouble with it working consistently when the car is on the go. Works fantastic sitting in the driveway. I was told by the vendor that the issue was likely electrical noise and that I needed to add a capacitor at the alternator, but this didn't resolve my issue. Have any of you had trouble with the electronic units and found an add on solution that works?
